# GNU make makefile
# This makefile uses GNU make specific conditionals.
#
# make arch=XXX
# where XXX is the architecture type as specified Matlab mex extensions
# examples:
#	mexsg64		64 bit SGI 
#	mexhp7		Helwett Packard
#	mexglx		GNU/Linux
#	dll		Microsoft win32
# These names are subject to change, consult your Matlab external
# interface guide for details.
#
# If you do not have GNU make on your system and do not want to
#	install it, simply remove the if.../else/endif directives
#	leaving the appropriate conditional code.
#
# Note - some system administrators install GNU make as gmake.

# Make sure we know what platform to build for.
